"Lightning Transient Suppression Circuit Design for Avionics Equipment" is an IEEE publication included with this download
This publication written by C. A. McCreary and B. A. Lail provides guidance for the design of avionics lightning protection circuits. This GUI allows the user to input the parameters of the transient for which they are designing protection and outputs the required information for component selection. The motivation for this GUI is to allow the selection of the smallest components that will tolerate the transient and provide adequate protection. Thus, the physical size of the interface assemblies housing the protection circuits can be minimized reducing the weight. This results in less fuel consumption.

Version Published Release Notes
1.6.0.0

There were issues with the latest version of this tool in which I tried to make it a stand alone app, so it has been reverted to just the .m and .fig files.Therefore, MATLAB is required to run it. The papers referenced in it are included also.
1.5.0.0

- Uses worst case rise time (-20%) and pulse widths (+20%) allowed by DO-160 for conservative design
- Allows unidirectional suppression devices to be used with waveforms from .txt files
- Uses Closed Form Calculation for trace width determination
1.4.0.0

- Uses worst case rise time (-20%) and pulse widths (+20%) allowed by DO-160 for conservative design
- Allows unidirectional suppression devices to be used with waveforms from .txt files
- Uses Closed Form Calculation for trace width determination
1.3.0.0

Return line impedance was not accounted for in the calculation of current, this change corrects this.

1.2.0.0

Corrected an error with Measured Voltage Peak.
1.1.0.0

Commented out "uiwait" in line 62 to eliminate a error that ocurred upon closing the GUI.
